Package Exports

@turf/clone

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@turf/clone) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@turf/clone

clone

Prevents GeoJSON coordinates from being mutated, similar to JSON.parse(JSON.stringify(geojson)).

Only cloning coordinates can be 3x-20x faster than the parse + stringify approach.

Parameters

geojson GeoJSON GeoJSON Object
cloneAll [Boolean] clones entire GeoJSON (3-20x slower if True) (optional, default false)

Examples

var line = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "LineString",
    "coordinates": [[-74, 40], [-78, 42], [-82, 35]]
  }
}
var lineCloned = turf.clone(line);

Returns GeoJSON cloned GeoJSON Object
